Hi Ross,

Thank you for the new version.Â Please see some more comments (in the usual CR format) on revision 01, I just saw you have revision 02, appologies if they are already resolved

Comment	Page No.	Subclause	SFD reference	Proposed Change (if applicable)
"The EHT-SIG field provides the necessary signaling in addition to U-SIG for the STAs to interpretate the EHT PPDU.". EHT-SIG helps both STA and AP to know allocation parameters and not limited to STA.	2	34.3.10.7.1
"A 3Ã—996+484-tone RU is referred to by seven RU Allocation subfields per EHT-SIG content channel, for both EHT-SIG content channels. The seven RU Allocation subfields per EHT-SIG content channel are labeled from the first RU Allocation subfield to the seventh RU Allocation subfield". Not very clear	4	34.3.10.7.3
Image Figure 34-x suggests that common field and user field get separate CRC and tail for all modes, whereas this is not decided yet. For example in the SU case a single shared CRC+Tail for common + user field may be of interest to fit 2 EHT symbols.	2	34.3.10.7.2		Add that the organization of CRC+Tail for compression modes is TBD for both common and user fields.
"In an EHT MU PPDU , an RU that is not allocated to a user can be indicated as follows (TBD):" Section is very unclear due to the TBDs. Relevant straw polls in compendium.	5	34.3.10.7.3	Straw poll #200	Compendium has more information (SP #200), update accordingly
The RU allocation subfield includes large size of RU aggregation for OFDMA transmission as follows: missing 2x996+484, and 3x996+484 M-RU	7	34.3.10.7.3	Motion 115, #SP72, [14] and [30]	add 2x996+484, and 3x996+484
Indicates the number of non-OFDMA users. Set to n to indicate n+1 non-OFDMA users. (Table 34-xx3 Common field for compressed mode) add that this is per RU (as also referenced later in the text)	9	34.3.10.7.3

Thanks,

Ron
